PLOW.

SPECIFICATION forming part of Letters Patent No. 764,713, dated July 12,1904.

Application filed November 4, 1903. Serial No. 179,839. (No model.)

To @ZZ whom 2215 may concern:

Be it known that I, CALVIN R. DAVIS, a resident of South Bend, in thecounty of St. Joseph and State of Indiana, have invented certain new anduseful Improvements in Flows; andI `do hereby declare the following tobe a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvementin plows, and more particularly tosulky-plows, the object of the invention being to provide improvedpivotal mounting of the cross-frame (carrying the land and furrowwheels) with the plow-beam and provide means under the control of theoperator for moving the land and furrow wheels at any desired angle toinsure the plowing of a straight furrow, especially in hillside work.

Tith this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is atransverse sectional view. Fig. 3 is an enlarged detail plan view. Figs.4, 5, 6, and 7 are enlarged views illustrating various other details ofconstruction.

1 represents the metal plow-beam, bent at its rear end, forming astandard 2, to which a suitable moldboard and plow-point are secured,and to the upper curved portion of the standard a bracket 3 is securelybolted and provides a vertical sleeve 4,'in which acrankshaft 5 ismounted, and carries the rear caster or follower-wheel 6, controlled bya foot-lever 7 to be hereinafter described.

The beam 1 about midway its ends is securely bolted to lugs 8 on acast-metal plate 9, supported on a larger plate 10, rigidly secured to across-frame 11 comprising parallel bars. The lower plate has an integralhollow journal or hub 12 projecting upward from its center into asimilarly-shaped box or hub 13, integral with upper plate 9. A bolt 14,

passed through a cross-bar 15 below frame 11, extends up between thebars of said frame through hollow journal l2 and has a large washer 16thereon, forming a cover for journal-box 13, and a nut 17 is screwedonto the lower end of the bolt 14, securing the parts together, butpermits free rotary movement of the journal 12 in box 13.

Between the bars forming cross-frame 11 said lever being pivoted to atoothed segment 24 on casting 18 and made with a springpressed detent 25to lock the lever in any position. It will be observed that bymanipulating lever 22 the crank-shaft 19 can he turned in eitherdirection to raise or lower this side of the frame and plow. Between thebars of frame 11, at its opposite end, a casting 26 is secured and ismade with a vertical bearing 27, suitably cored to fit a bar 28, I shapein cross-section. To the lower end of this bar 28 a casting 29 isadjustably secured by setscrews 30, cored to receive a furrow-wheel-axlestub secured in place by set-screws 32 and having a furrow-wheel 33mounted thereon, said furrow-wheel being preferably smaller than theland-wheel, as shown. A toothed segment 34 is secured to casting 26 andis made with a forwardly-projecting arm 35, having a bearing at itsforward end for a bolt 36, on which a lever 37 is fulcrumed, andprovided with a spring-pressed detent 38 to lock with 'segment' 34. Arod-link 37 connects a bracket 37b on bar 28 with a similar bracket 37con lever 37, thus compelling' thc bar 28 to move vertically in thebearing 27 when the lever 37 is operated. A small bracket 39 is alsosecured on bolt 36 and is connected with a similar bracket 40 on theupper end of bar this lever 43 and at its opposite end is pivotallysecured by a colter-pin in an eye-bracket 46, fixed to the plow-beam lnear its forward end. It will thus be seen that the operator may bymanipulating the landing-lever 43 change the line of travel of both thefurrow and land wheels either tothe right or left, as may be required.This is avaluable feature, especially in hillsidev plowing, as theoperator may by this improvement cut an even-width furrow when throwingthe soil up or down on the hillside. He is also enabled to straighten acrooked furrow, regulate the width of cut, and turn a square corner atend of furrow.

To the upper end of rear caster-wheel crankshaft 5, above referred to,an arm 48 is secured. and a rod 49 is pivotally connected to this arm,projects forward through a bracket 50 on a bell-crank foot-lever 7, andhas a head or enlargement on its forward end. The foot-lever 7 isfulcrumed on a bolt 51, passed through alined openings -in parallel ears52 on castingplate 9, and said lever 7 has a lateral lug 53 on itsforward member, which when forced. forward to lock the caster-wheel inworking position will rest upon and depress the forward arm of areleasing foot-lever 54, fulcrumed between its ends on bolt 5l, so thatwhen the foot-lever 7 is in its forward position the operator can bypressure on lever 54 release said lever 7 from such position and permitthe plow to line to the right. No release is necessary in turning to theleft, as the rod 49 is free to move forward in bracket 50.

A great many changes might be made in the general form and arrangementof the several parts described without departing from my invention, andhence I would have it understood that I do not restrict myself to theprecise details set forth, but consider myself at liberty to make suchslight changes and alterations as fairly fall within the spirit andscope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a sulky-plow, the combination with a cross-frame provided withbearings for land and furrow wheels, of a frame-plate secured to thecross-frame, a beam-plate mounted upon the frame-plate, a beam securedto the beam-plate, means pivotally connecting said plates, anoperating-lever mounted on the cross-frame and a connection between saidlever and the plow-beam.

2. In a sulky-plow, the combination with a cross-frame provided withland and furrow wheel bearings, of a plate pivotally connected with saidcross-frame, a plow-beam secured to' said pivoted plate, a caster-wheel,a connection between said caster-wheel and said pivoted plate, a levermounted on the cross-frame and a connection between said lever and theplowbeam for turning the beam and pivoted plate to which it is secured.

3. In a sulky-plow, the combination of a cross-frame, a beam, a pivotalconnection between said cross-frame and the beam, a casterwheelsupporting the beam at its rear end, of a land-wheel crank-shaft havingrotary mounting in one end of the frame, a land-wheel on said shaft, alever to turn the shaft and raise and lower this end of the frame, meansAfor locking the lever in any position of adjustment, an angular bearingat the other end of the frame, an I-bar mounted to move vertically insaid bearing, a furrow-wheel connected with the lower end of said I-bar,and means for raising and lowering the I-bar in the bearing to raise orlower this `side of the frame, a lever mounted on the cross-frame and aconnection between said lever and the plowbeam.

4. In a sulky-plow, the combination with a cross-frame, land and furrowwheels connected therewith, and a beam supported on said crossframe, ofa bracket at the rear end of the beam, a crank-shaft mounted in abearing in said bracket, a caster or follower wheel on said shaft, anarm secured on the upper end of the shaft above the bracket, abell-crank foot-lever fulcrumed on the cross-frame, a bracket on onemember of said lever, a rod pivotally connected with said arm, passingthrough an opening in the foot-lever bracket and headed at its forwardend, so that when l the foot-lever is pushed forward the followerwheelwill be held in working position, and another foot-lever fulcrumedbetween its ends on the cross-frame and adapted to engage a lug on thebell-crank foot-lever and release the latter from locking position whensaid last-mentioned foot-lever is depressed.

5. In a sulky-plow, the combination of a main frame, a cross-framecarrying bearings for land and furrow wheels, a plate pivotallyconnected with said cross-frame, a beam secured to said plate, acaster-wheel at the rear end of the main frame, a bell-crank foot-leverpivoted to said plateand adapted to lock the IOO IIO

caster-wheel in working position, and a secl ond foot-lever also carriedby said plate and adapted to release the bell-crank lever from itslocked position. n

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
